5E4B HALLPPP

Hey guys,

Since I've owned my MCS, I have had this code stay on...

It reads: 5E4B "Pressure Sensor Sensor Error Offset"
With further research, I have been led to the rear-right of the vehicle.

What I have done:
1. Replaced ABS and brake wear pad sensors (with the mod to make it seem like the pads are perfect all the time)
2. Unplugged each sensor to see if any new codes popped up or not. When done, new codes popped up for that rear side pointing me to each sensor I disconnected.

Could it be as simple as the right rear TPMS is malfunctioning??? What else back there would be pressure???

TIA

That is a real interesting code. See I don't know everything:unsure:. Codes like that is the reason why I have two different mini cooper specific scanners. One day though I will get the AUTEL; 500 dollars (U.S.) version.
But until then May I ask a question?
Does the scanner you have show the code and what it means. With the code on the left hand side and a abbreviated message of what it is on the right; along with the option to click the code and brief message in exchange for a longer iterated version of what it means? If Not
That is one reason I recommend that foxwell NT530 for mini cooper scan tool. I figured that out about a month after I owned it. It's still simple but with a in depth statement about the code. I said I can do this!(y)

So my scanner is an INNOVA 3100RS that can read Standard OBDII, Mini ABS, Mini Specific codes, and others.

It really doesn't show much more than the standard message I posted, but I found a list of BMW codes and read the specifics of said code to ascertain the location of the error. Why they have to be so complicated? who knows haha.

Ill keep digging! Thanks for the input :)

In 2021 I think the best scanners are the ones that offer consistent updates. That what Foxwell sent me in a email last week to update it. And in the update there is a mini cooper update. Not just a generic update; a update for the NT530 foxwell.
But it's like computer updates always read the update to see if you need or want it.

truth. It looks like there is a software update for my tool that came out late 2020. Looks like I'll be plugging it in when I get home
This is the right rear:

1) ABS sensor circled in red.
2) Fuel Tank Leakage diagnosis module (DMTL)
3) Brake wear sensor line Red Arrow
4) ABS Sensor wire.
This is the left rear:

B4.)ABS wheel speed sensor
B45.)Tire pressure control (RDS) sensor
B64a.) Rear ride height sensor
X376.)connector
X13251.)connector
X18037.)connector
So here it states that the tire pressure is on the left rear side.

The red arrow in this picture points to where the connection for both the ABS and the Brake wear sensor are.
You may have a Bad (RDS) sensor. If not a TPS sensor.
